zen of the United States, anda resident of Brooklyn, in 'the county oflings andvStat'e of New York, have invented certain new and v useful Improvements in Burners, of whichv `the following is a specification.

This invention is an improvement in burners for hydrocarbon or other liquid or f semidiquid. fuels in whichv they fuel is sprayed or delivered'in atomizers or vaporizersformed bythe action of a jet of some expansible gaseous medium, such for in-g stance, as steam or compressed air. invention 1s an improvement on the type of f burner shown inthe Best Patents 708,453, and 752,195. In the constructions shown in said patents, there is provided a fuel passage terminating in an upwardly directed outlet and a passage for the eXpansible gaseous spraying medium terminating in an v.

outlet directed substantially at'right angles across the'fuel outlet. The steam or air passage has a mouthpiece normally clamped in position but movable upwardly to facilitate cleaning 'or the removal of obstructions p' within the outlet.

yMy invention relates primarily to theconstruction of this movable mouthpiece and its connection to the remainderl of the burner and its operating mechanism, so that the mouthpiece may be moved to free the out-k let from .obstructions without raising it away from the supporting surface" with which it cooperates to form the gaseous men dium outlet. By means of my construction,

it is possibleto adjust the position of the` gaseous mediumoutlet toward or from the f fuel outlet without varying the sizes thereof,

and without interfering withthe operation of the burner. Should scaleor' other foreign substance clog the atomizer orifice, itvca-nbe removed lby loosening rthe securing means and allowing the' movable mouthpiece or atomizer lip to pass over the fuel outletsol Y that the substance clogging thepassage will be deposited in vthe .fuel orifice.. Upon; the

return of the lmouthpiece or atomizery lip fto. its original position, the operationofthew; burner willcause theV foreign substance to` pass out with the fuel; `The construction is Vsuch that carbon cannot form nor solidify".A over the'atomizer and the yatomizer lip has.

a sliding connection of'such formf that in ra'rsnrorr yApplication led June 3,

l ntheaccompa'nying drawings to which lreference, is to be had, l have shown certain forms which my invention may assume, al!` though 1t is'evldent that I do not wish to' ted to such specific` constructions.

be restrie In these drawings: Figure 1 is acentral longitudinal ysection through a burner. constructed in accordance with my invention, and particularly adapted for smallsizes, saidfsection being takeny on the linel 1-1 of Fig. A

the heating of loc` omotives,andy

- Fig. is atop plan view ofthe form shown', in Figl. f l Y inthe burner shown in Figs. 1, 2, and 3,

l employ Va body yportion 10 preferablyV formed from a single casting of brassuor other suitablematerial, and having passages 11, and 12 therethrough, the formerbeing for the liquid or semi-liquid `fuel andthe latter for the'steam, compressed air,l Lor other fatornizing'fluid. Each ofthese passages has a threaded inlet orother construction adapting'. it for attachment tol suitable supply pipes. The fuel passage 11 has anupwardly facing outlet k13, terminating in a vflat face or table -portionl ofthe burner.l The outer` wall of the passage is out away or formed with a. recess 15V below the plane -of the surface 14 and flaring Vsomewhat as shown particularly in F-ig. 2.

The passage. 12 for the atomizing medium tween the," surface 14C and a movab'lermouthpiece or atomizer lip .177. This orificeis'pref- 95. 'i 'terminates in an outlet orifice l16v formed beerably slightly wider thannthe fuel outlet i orifice 13, and is preferably lslightly higher at its side'edges than at its middle-portionas shown particularly in Fig. 3, so that there- 1 sulting fan-shaped spray .or sheet'of fuelfwill sideportionsy as atthemidd'le portion'.4 The 3 atomizer'li'p-is mounted so that it .mayslide alongl the surface 151. yin a ldirection at'right angles to,the1outlet,13 andmay thus approach orrecede from the latter without being adjusted, it ?does.11ot leave'its. seat asjlyarying the sizeporshape ofthe atomzerg,

besubstantially of the samethickness :at the I orifice 16. The member 17 is shown as fitting 'into a recess beneath an upper flange 18 which prevents it from moving away .fromv Y. the surface 151 and has suitable operating means movable back and forthwithin said recess. This operating means 1s shown as a bolt .19 extending through a passage in the.

body of ltheburner and rigidly secured to the member 17. Y Theboltvat its rear end has a nutf20 by the tightening of which the A`mouthpiece may be drawn back toits limiting position. As it is not ordinarily desirable to permit the member 17 to' move en* Q i tirely out'of thel recess or to be separated .15

from the balance 4of the burner,` the bolt preferably has a Cotter pin 2,1 limiting the movement ofthe nut Q0. The relative proportions of the partsis such that by screwing the nut back so that it engages the cotter pin,ftli`e member 17 may move forward until the atomizer orifice 16 is over the fuel orifice but the member 17 will still be held down by the flange 18. rlhe flange 18 may if desired be entirely omitted, and other means utilized Afor preventing theupward movement Vof the mouthpiece. The body has a pair of dowel pins 22 disposedwithin-corresponding re-` cesses ,in the mouthpiece 'so as to 'guide the l mouthpleceand prevent any upward movement of the latter. These will yhold the v mouthpiece down in proper position even though the mouthpiece be moved out beyond the lflange 18 or even though the latter be omitted. Therear or inner surface of the recesses andthe corresponding surface of fthe mouthpiece are shown as being beveled .'or' inclined downwardly and inwardly so thatwhen the rmouthpiece is drawn back to its limiting positionkit will at the same time bev forced downwardly and held firmly iagainst the supporting surface 14 of the burner.' Thusthe tightening of the nut not only holds the atomizer lip tightly` to the y body of the burner -but'also Afurnishes the desired pressure to held the atomizer lip fdown and insure the joint being hermetically'l'sealed. The flange 18 not lonly serves to hold the mouthpiece down but protects these inclined surfaces and prevents any foreignv substance` from falling vfrom the fire box and getting in between the atomizer lip fandthebodyv ofthe burner when the nut and the blt are loosened.

4 It will be noted that 'the bolt 19 does not pass through the expansive fluid passage '12' (but throughV a separate and independent 'vzpasls'age inthe wall ofthe burner. The inclined rear surface of the nozzle piece seats against the-inclined Lsurface ofthe burner frpacking of any kind is required for the bolt, the steam or'. other expansive fluid ean- A not gain access to the bolt passage when'thefV :both above this belt and below'itso `that no :nozzle member is in place.

'In the larger constructin'ShOWI-i Vin Figs.

4 and 5, the same principle of operation, is employed Yalthough the Adetails are somewhat different. Duefto the greater width of the mouthpiece 17a, this is provided with two parallel clamping bolts 19a-19a These may extend through lugs or flanges 23 and 2linstead of through passages in the body of the burner as shown in F ig. 1. Insteadof hav-l ing the bolts` rigidly secured to the mouthpiece, the latter 4may have fslots- 25'tl1erein receivingthe square vh eads 26 of the bolts.

Byfremoving thev cotter pins 21, and entirely removing the nuts 20, the ymouthpiece may be moved out entirely beyond the `end ofthe body 10a and then lowered out ofoperative engagement with .thek bolts;

In this form, Vthe body -10il has formed integral therewith lugs 27 whereby the burner may be clamped,

or otherwise'se'cured in position, and the inlettothe fuel passage 113L is shown as extending up from the bottom and the inlet to the atomizing passage 12 extending in from the side instead of both from the rear as in YFi 1.

y improved 'construction' is cheap, durabl'e, and made of a minimum number nfVV parts. The outlets may be so formed as to 4give any desired width of flame by varying the flare of the' recesses 15 shown in Fig. 2

or this flare may be eliminated and the sides made straight as shown in Fig. 5 lso as to 4give a long 'straight flame. The outlet for the expansive fluid being wider than the liquid fuel outlet, the expansive fluid `thoroughly covers the fuel outlet and prevents any droiling or dribbling of fuel from the nose of the burner. When a short flame is desired, the opening for the expansive fluid is very small in height but when a long flame isr required the openingis proportionately` delivered under pressure sufficient to over-Vv come this compression action. vAs the boiler outlet varies. k,The device automatically regulates itself as a lower steam pressurepervmits of an increase-in the voutflow of oil or other liquid fuel dueto the lowered compressing" action of the expanding steam on the liquid fuel outlet..V
